Modern zen4 based laptops can get 15 hours. My 2019 MBP was quoted as 10 hours but gets under 2.... Why? because it's more software than hardware that is the issue. My MBP runs out of battery quickly because outlook (or chrome) uses too much CPU and it drains quickly and runs hot. You get the 10 hours only if then SW lightly loads the CPU. This is the same for Zen and appple Mx CPUs. If you run exactly the same apps you will get similar performance.... The modern zen are very efficient CPUs.
Usually for me the culprit for poor battery life is MS office apps, but under MacOS I've seen window manager consume 90% CPU regularly.
Long story short, buggy SW dictates battery life on modern laptops, with very little between apple and zen (can't speak to modern Intel CPUs, i dont have a laptop with one)
- piva00 2y agoYour 2019 MBP is running Intel chips, not at all comparable to the 2020-onwards M processors. I also had a 2019 MBP kitted out as a work computer before and it barely lasted 3h on a normal workday (meetings, compiling code, running Docker, many, many tabs open on browsers, etc.); my work M1 Max lasts anywhere between 8-12h on a heavier workload than what I worked with in 2019 including all I mentioned in the parenthesis. So yes, software is the culprit but the M-series are much better at managing the same software (and even heavier ones) that I run, for the same job.
- tails4e 2y agoI'm well aware it is Intel, but it was still sold at the time as a 10 hour battery life, and I'm sure it can be, when nothing is running but one tab of safari. So my point was, and in agreement with you, is when using similar sw (buggy or not) a modern zen4 will have similar battery life to a M1 / M2
